I got my hands on a Specialized S-Works Tarmac SL8 - Shimano Dura-Ace Di2 for a couple of months and clocked up thousands of kilometres of testing in London, the home counties and Girona.
Since I first rode the Specialized Tarmac SL8 last year, it has remained my benchmark. Its blend of speed, responsiveness, comfort, and practicality is still unrivaled in the race bike market.
